如何在AchartEngine Android中设置轴宽度和高度？

Question

（1）欲X和Y轴宽度和高度， （2）欲X轴标贴适当对准 （3）我想改变值的文本的颜色，当前是橙色和我想要白色。

我的代码是：

private GraphicalView mView(Context ctx) { 
     GraphicalView v = null; 

     String[] titles = new String[] { "" }; 
     List<double[]> values = new ArrayList<double[]>(); 

     double[] mDoubleArray = { 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 
       0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 
       0.0, 0.0, 0.0, 0.0 }; 

     String[] X_Axis_Lables = { "07:00", "08:00", "09:00", "10:00", "11:00", 
       "12:00", "13:00", "14:00", "15:00", "16:00", "17:00", "18:00", 
       "19:00", "20:00", "21:00", "22:00", "23:00", "00:00", "01:00", 
       "02:00", "03:00", "04:00", "05:00", "06:00", "07:00" }; 

     values.add(mDoubleArray); 
     int color = getResources().getColor(R.color.actionbar_header_color); 
     int[] colors = new int[] { color }; 

     XYMultipleSeriesRenderer renderer = buildBarRenderer(colors); 
     setChartSettings(renderer, "", "", "", 0, mDoubleArray.length, 0, 1, 
       color, color, X_Axis_Lables); 
     renderer.getSeriesRendererAt(0).setDisplayChartValues(true); 
     renderer.setXLabels(0); 
     renderer.setYLabels(1); 
     renderer.setXLabelsAlign(Align.CENTER); 
     renderer.setYLabelsAlign(Align.LEFT); 
     renderer.setPanEnabled(false, false); 
     renderer.setZoomEnabled(false, false); 
     renderer.setZoomRate(0.0f); 
     renderer.setShowLegend(false); 
     renderer.setBarWidth(10); 
     renderer.setMarginsColor(getResources().getColor(
       R.color.transparent_background)); 
     renderer.setApplyBackgroundColor(true); 
     renderer.setBackgroundColor(Color.TRANSPARENT); 
     renderer.setXLabelsColor(getResources().getColor(R.color.gray)); 
     renderer.setYLabelsColor(0, Color.GRAY); 

     v = ChartFactory.getBarChartView(ctx, buildBarDataset(titles, values), 
       renderer, Type.STACKED); 
     return v; 

    } 

    protected void setChartSettings(XYMultipleSeriesRenderer renderer, 
      String title, String xTitle, String yTitle, double xMin, 
      double xMax, double yMin, double yMax, int axesColor, 
      int labelsColor, String[] x_Axis_Lables) { 
     renderer.setChartTitle(title); 
     renderer.setXTitle(xTitle); 
     renderer.setYTitle(yTitle); 
     renderer.setXAxisMin(xMin); 
     renderer.setXAxisMax(xMax); 
     renderer.setYAxisMin(yMin); 
     renderer.setYAxisMax(yMax); 

     for (int i = 0; i < x_Axis_Lables.length; i++) { 
      renderer.addXTextLabel(i + 1, x_Axis_Lables[i]); 

     } 
     renderer.setXLabelsAngle(270); 
     renderer.setLabelsTextSize(16); 
     renderer.setAxesColor(axesColor); 
     renderer.setLabelsColor(getResources().getColor(R.color.gray)); 
    } 

    protected XYMultipleSeriesRenderer buildBarRenderer(int[] colors) { 
     XYMultipleSeriesRenderer renderer = new XYMultipleSeriesRenderer(); 
     renderer.setAxisTitleTextSize(16); 
     renderer.setChartTitleTextSize(20); 
     renderer.setLabelsTextSize(15); 
     renderer.setLegendTextSize(15); 
     int length = colors.length; 
     for (int i = 0; i < length; i++) { 
      SimpleSeriesRenderer r = new SimpleSeriesRenderer(); 
      r.setColor(colors[i]); 
      renderer.addSeriesRenderer(r); 

     } 
     return renderer; 
    } 

    protected XYMultipleSeriesDataset buildBarDataset(String[] titles, 
      List<double[]> values) { 
     XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset(); 
     int length = titles.length; 
     for (int i = 0; i < length; i++) { 
      CategorySeries series = new CategorySeries(titles[i]); 
      double[] v = values.get(i); 
      int seriesLength = v.length; 
      for (int k = 0; k < seriesLength; k++) { 
       series.add(v[k]); 
      } 
      dataset.addSeries(series.toXYSeries()); 
     } 
     return dataset; 
    }

试试这个：

renderer.setAxesColor(Color.BLACK); 
    renderer.setLabelsColor(Color.BLACK); 
    renderer.setXLabelsColor(Color.BLACK); 
    renderer.setYLabelsColor(0,Color.BLACK); 
    renderer.setYAxisMax(200); 
    renderer.setXAxisMax(200);
